    I got a bit behind with replying to some emails (about 50), so thought I would catch up with them yesterday

    Reply is just a quick copy n paste so I just started replying to them at about 15:00

    I was probably sending 2 or 3 a minute for about 15 minutes but then got an error message
    451 4.3.2 internal server error.

    I'm guessing it is a built in ant-spam measure, but how many is too many emails?
    Would it be frequency I was replying rather than the actual quantity?

    Could be anything depending on your server set up and hosting plan.

    You can limit based on quantity per hour and how frequently a mailbox is sending.

    If I remember rightly, most of our default hosting plans are set to sending a max of 50 emails per hour.

    Should it automatically reset after a while or do I need to contact host to get them to unblock something?

    It will depend on the server configuration. Contact your host.

    Should be automatic. If there is a flood limit in place (sounds likely) then try again after 5 minutes and it would usually work again. Unless your host has something even more stricter in place that freezes sending for half hour or an hour or something (which is also doable).

    I would start shopping around for a decent email provider. Blocking below 50 emails an hour is a poor setup and decision by them. 10 emails a minute should be the bare minimum allowed to run as a business setup. Most decent providers give you easily 25 or more emails per minute before spam is triggered.

    Exchange Online or Microsoft 365 Business Basic is cheap as chips and has rate limits of 30/minute and 10,000/day. Worth a thought.

    You could also consider a transactional email solution like SendInBlue.
